COOKING s'rovn.

App'iiaton ined November 21, 1922. serial No. 602,444.

To all 'whom concern.'

Be it known that I, Farra ALBERT Pn'rrnns SON, subject of the King of Sweden, residnig' at Halnistad, Sweden, have invented certairiiiew and useful Improvements iii Cooking' Stoves, of which the'ifollowing is a specification'. Y

The present invention relates to a cooking stove" containing a baking oven and a hot water containenin which the latter is coinposed of several elements, situated at the back of the stove. Acc'Ordingl to this invention two dainpers are arranged in the smoke fiile' of thestove, the oneJ at the entrance'to' the flue around' the 'said elements and` the otherV inthe iiue aroundV the baking oven. The saidfdampers" aire arrangedin such a inann'e'rthat when the damper in the element nue' is open and thevother damper 'shut the gasesfrorn the lire flow directly between'the two Velements of the hot water container, which are situated nearest to the fire place and from thence between the other elements.

whilst in the reverse position of the dampersr the' gases from the lire place" are caused to now through tl'ie'iiuearound'the baking ovenand from thence to the/flue of the hot water containing elements, without, however. passing through that part of the' 'said flue' which is'V situated between the two' elements nearest the fire place.

yA constructional forni oftheA invention isV illustrated'in the accompanying drawing, on whichFig. 1 is a Vertical longitudinal section of the stove andFig-, 2 isa vertical cross section on the line Il llf (Fig. 1). Y

- 1` s'the ,replaca betweenwhich and the smoke outlet 2 the hot water contaii'i'er,

heated by the gases from the tire place, isV

situated.V 'This containerV in the form',` illustrated as an example, consists of three ele; ments 3, 4 and5, communicating with and secured behind oneanother Vin" such a man1-j ner that vertical channels orV passages 6, 7 are formed between them. The front element 3 formsltlie back wall of the lijeplaceV element 4, as ill-ustrated by the arrows, Fig. 2. The intermediate element 4 is made with a central opening 9 -in its lower part and the rear eleineiit is inade'with a central opening near its upper end so that the gases r in Fig. 2). the fire gases thus flow downy through the passage 6, through the opening 9 and upwardly through the passage 7 between the two elements 4 and 5, and from thence through the opening iii the element 5 to the smoke outlet'Q.. The passages 6, 9 and 7 thus constitute tlues which may con- Vey the lire gases between the saideleinents to heat the water therein.

' The baking oven 10 is located at one side of rthe fire-space and of the water heater, and extending across the top of the oven 1() isa passage 16 which communicates with a' passage 17 at the side of the oyen7 which passage 17 communicates in turn with a bot! sagesl 17, 18 as shown, it may obviously be y situated at any position in the said passages( This cooking stove and water heater operates in the following nianneiw-W7heii the damper 1 1 is open and the damper 12 shut (thusjclosing the passagethrough the passages 16, 17 and 18 .around the bak-ing oven) the hot gases from the fire place 1 flowy through the opening 8 in the upper part of t-he elementand pass downwards through the passage 67 through the passage 9 and upwardly through the passage 7 to the smoke outlet 2, whereby the water in the elementsV 3, 4t, 5 becomes heated'to a high temperature.

1f it be desired to heat the baking oven 10,

`passage 18 to the passage 9 and from thence to the passage 7, without iiowing through the passage 6 between the front and the interinediate elements of the water heater.

The damper 11 is loosely/fitted in a recess in the uppeirpart of the intermediate element et, the damper door itself being pivoted in a frame 19, provided with grooves 20 or flanges at the sides and the lowerI edge,

which grooves or iianges coopera-te with corresponding iianges 21 or grooves in the said element il. rBy means of this arrangement a very simple construction of damper is provided, and moreover, a third passage for the tire gases may be provided by moving the damper 11 so that the gases from the fire place may iiow freely through the opening in the upper part ofthe' element i (otherwise occupied by the damper) directly to the smoke outlet 2, and without flowing through the passages 6, 9, 7 oi' through the passages 16, 17, 18.

Having now particularly described the nature of my invention and theA manner of its operation, what I claim is:

1. A cooking stove and water heater com prising,-a'fireplace, awater heater located behind the fireplace and comprising front, intermediate and rear water containing elements spaced lfrom each other to form vertical front and rear ypassages for the fire gases, a baking oven located at one side of the fireplace, means aroundthe oven forming passages for directing the lire gases over the top of the oven, thence down one side, and thence beneath the bottom thereof, means forming a passage for directing the said gases from beneath the ovento the said vertical rearpassage between the intermediate'and rear water containingv elements, and control means for the vfire gases y vcomprisinga damper for shuttingy oif the flow of 'gases around the ovenand a secondk damper for controlling the flow of gases through the saidverticalfront passage whilst the iiow through the said vertical rear passage is uninterrupted. 4

V2. A-cooking stove and wat-er heater com- Vprising,-'a fireplace, a waterheater located behind the fireplace 'and comprising front, intermediate and'rear waterV containing elements 'spaced from each other to form vertical front and-rear passages for the fire gases, a bakingoven located at one side of the fireplace, means around the oven forming passages 'for directing the fire gases over the top of the oven, thence down one side, and thence beneath the bottom thereof, means forming a passage for directing the said gases from beneath the oven to the said vertical rear passage between the intermediate and rear water containing elements, and control means for the lire gases comprising a damper located in the gas passage beneath the oven for shutting off the flow of gases around the oven and a second Vdamper located between the vertical front .and rear passages for controlling the iiow of gases through the said 'front passage whilst the flow through the said rearpas-L sage is uninterrupted.

3. A cooking stove and water heater comprising,-a fireplace, a water heater located behind the fireplace and comprising front, intermediate and rear water containing elements spaced from each other to form vertical front and rear passages for the fire gases, the intermediate 'water containing element having an opening at the upper edge thereof, a baking oven located at one side of the iireplace, means around the oven forming passages for directing the lire gases over the top of the oven thence down one side and thence beneath the bottom thereof, means'sforming a passage for directing the said gases from beneath the oven to the said vertical rear passage be-` tween the intermediate and rear water containing elements, and control means for the iire gases comprising a damper for shutting oli' the flow of gases around the oven, a second damper for controlling the iiow of gases through the said vertical front passage whilst the flow through the said rear passage is uninterrupted, and a movable member closing the said opening in the intermediate element and carrying the last mentioned damper. l

4. A cooking stove and water heater comprising,-a fireplace, a water heater located behind the fireplace and comprising front, intermediate and rear water containing elements spaced from each other to 'forni vertical front and rear passages for the fire gases, the intermediate water containing element having openings at the upper and lower edges thereof, a baking oveny located at one side of the fireplace, means around the oven forming passages for directing the fire gases over the top of the ovenY thence down one side and thence beneath the bottom thereof, means forming a passage for Vdirecting the said gases from beneath the oven through the said opening in the lower edge ofthe intermediate element to the said Yverticalrear passage between the interme- .'e rying the latter damper and mounted in the Witnesses:

for controlling the HOW of gases through the In testimony whereof I aix my signasaid vertical front passage Whilst the flow ture in presence of tWo Witnesses.

throuofh the said Vertical rear passage is unintrrupted, and a moveable member oa- FRITZ ALBERT PETTERSSON' upper opening in the said intermediate ele- A. MAHLIN, ment. v GEORG C. JUNIUs.
